Application tiled May 1'2, 1888. Serial No. 273,730.

To @ZZ whom. it may concern.-

Beit known that I, WILBUR F. STEELE, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Car-Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains'to make and use the same.

My invention relates to a ear-heating apparatus of the class in -which air is heated by means of a suitable burner and discharged through a Hue into a space inclosed by and beneath the seat of the car or into the body ofthe car itself, and in which the radiating heat from the pipe carrying off the smoke and products of combustion from the burner is also'employed for heating the air.

Theinvention consists, generallyin the construction and combination of parts hereinafter described, and particularly pointed out in the claims.

The object of my invention is to provide sim ple, inexpensive, and durably-constructed carheating apparatus, which is not only adaptable to new cars, but to those of the present ordinary construction, which is capable of bcing taken apart and removed, and which is arranged beneath only one car-seat and only on one side of the car, thus avoiding the employment of heating apparatus under each carlseat and on bot-h sides of cars.

In the accompanying drawings, forming a part of this specication, and in which the same reference-numerals indicate the same parts, Figure 1 represents a longitudinal vertical section of a street-car and a heating apparatus therefor, the front of the seat being removed. Fig 2 is a detail showing a modified construction ofthe drum and core in the smoke- Fig. 3 is a vertical transverse section on the line x v of Fig. 1. Fig. 4 is an enlarged transverse section on the line y y of Fig. 1, and Fig. 5 is a broken longitudinal section of the lower portion of the car in front of the seat.

In the drawings, 1 represents the bottom or door of the ear; 2 and 3, the ends of the same; 4, the top of the seat, and 5 the front of the $311118..

(No model.)

` The front 5cl" theseatisprcferablyprovided with a comparatively wide slot or opening, 6, near its upper edge, and with a narrower slot or opening, 7, near its lowcredge. Theseslots or openings p referably extend the entire length of the seat, and they may be left entirely open or have perforated or register' plates secured thereover. An aperture or opening is preferably formed in the bottom of the car ata point about midway of its length, and in this is arranged a suitable casing, 8, which may be secured to the bottom .of the car in any suitable manner. W'ithin this easing is arranged a suitable hydrocarbon burner, 9, which may be of any preferred construction.

A tank or reservoir, 10, is preferably arranged at one end of the car beneath the projecting hood 1l, and asupply-pipe, 12, extends from the tank 10 to the burner 9. Through this pipe liquid hydrocarbon is supplied to the burner 9, where it is vaporized and burned in the usual manner. Iy may provide the tank 10 with an indicating-float, 13, connected toa pivoted lever, 14, the other end of which is connected to a rod, 15, extending downward through the part of the roof that projects over the platform of the car. This rod is provided' with a button, 16, at its lower end, the posi-` tion of which will show the amount of oil in the tank.

A casing, 17, having preferably an open bottom and a closed top, is arranged within the casing 8, and constitutes the main part of the heater. The upper portion ofthis casing communicates with a smokepipe,18, extending to one end of the car. This smoke-pipe is preferably formed with a drum, 23, arranged in it between the heater and the end of the car, and havinga dru ni or core, 19, supported longitudinally within this drum 28. The ends of the core 19 are preferably made pointed or conical in shape, so as to not retard the passage ofthe smoke and products of combustion. The end of the pipe 18 is connected to a pipe, 20, which extends upward through the inclosed space in the end of the ear and passes out through the top ofthe car; or, ifpreferred, said pipe 2O may be extended backward beneath the seat and pass out at the top of the other end of the car. In either event it may be provided with a pipe, 21, at its discharge end projecting abovc the roof of the car for the more ready escape of the products of combustion. In some instances the core 19 may be made hollow, and may project through the ends of the drum 23, and a plate, 2i, may be arranged spirally in the annular space between the core 19 and the drum 23. A iiue, 25, open at each end, extends through the casing 17 of the heater directly above the burner 9. One end of this tlue communicates with the open space beneath the seat of the car, and the other end is connected to a iiue, 27, which extends in the space beneath the seat nearly to the end of the car, and opens into this space, or is carried out to the front of the seat and communicates directly with the interior of the car. The smoke-fine 1S and the hotair iiue 25 extend in opposite directions from the heater to the opposite ends of the car through the space beneath the seat. I may also provide the flue 25 with a series of pins, 29, iro jecting into the interior flue, and projecting also from the exterior thereof. These projecting pins may be inserted through the flue or they may be cast integrally therewith. These pins increase the heating capacity of the flue, causing it to more readily become heated and increasing its radiatingsurface. I also prefer to provide in someinstancesa pipe, 31, of less diameter than the i'lue 25, having its open end projecting into the open end of the due 25, as shown in Fig. 1. This pipe extends down through the bottom ofthe car, and is provided at its lower end with two funnel-shaped mouths, 33, each communicating with the pipe 31, and opening in opposite directionsone toward the front and the other toward the rear of the ear. A similar pipe may, if preferred, be arranged in connection with the core 19 and drum 23.

Vhen the burnerislighted, the heat from said burner willcause thecolderair,which entersthe space beneath the seat through the lower slot or opening, 7, to pass through the iiue 25 and be heated by the ilame from the burner, which is immediately below said ilue. The heated air then aseends through the hot-air iiue 27 and is discharged into the space beneath the seat, whence it escapes through the upper opening, 6, into the car and heats the same, or it is discharged directly into the space between the seats. The products ofcombustion which arise from the burner and pass around the flue 25, within the casing 17, first heat said casing and the surrounding air by radiation an'd then pass into the smoke-pipe 1S and pass toward the end of the car which is opposite to that toward which the heated air is conducted by the flue 27. IVhen the smoke and products of combustion arrive at the drum 23 and core 19, they will be spread out and distributed over the entire inner surface of said drum and inipart their heat throughout the same, which will cause a greater radiation of heat to take place from said pipe than would occur were it wholly unobstructed; also, the smoke and products of combustion thus come in contact with a larger surface than they would in un` obstructed pipes, having necessarily a comparatively smaller diameter, so as to not produce too great a draft upon the burner. Vhen the open core is used, as shown in Fig. 2, a circulation of air will also be obtained through this open core, thus increasing the heating capacity of the drum. The air beneath the seat will thus not only be heated by radiation from the heater itself, but toward one end of the ear itwill be heated by the heat radiated from the iiue 27 and also by the hot air discharged through this iiue, and toward the other end of the car by the intensified additional heat radiated from the smoke-pipe 18 and the drum 23. rIhe pipe 3l also creates a current through the iiues 25 and 27. The heated air from the space beneath the seat escapes through the upper opening, 6, into the car,while the colder air to be heated enters at the lower opening, 7, at the front of the seat.

It will be obvious from the foregoing that new street-cars or those of the present ordinary construction can be readily provided with this heating apparatus, as it will only be necessary to have an opening in the floor be neath the seat and the slots or openings in the fronts of said seats. Then the inner and outer casings, t-he burner, the supplypipe, the hotair flue and the smoke-pipe are placed in position; also,whenever it is desired, said heating apparatus can be taken apart and removed.

Having thus fully described the construction and arrangement or combination of the parts of my car-heater, its operation, and advantages, what I claim to be new is* 1. In a car-heating apparatus, the combination of a casing and a laterally-extending smokepipe at or near the top of said casing, provided with a drum and an interior core, a ilue extending through the sides of said casing and having one end open, and a hot-air flue secured to the other end of said Hue and extendingtoward the end of the car, anda burner arranged in the bottom of said casing.

2. The combination, with a ear, oi a heater arranged in the space beneath the seat, a smoke-pipe connected with said heater and extending beneath the seat to one end of the car, an open heating-flue extending through the heater, and a hot-air tine connected with said heating-due and extending in the space bcneath the seat to the opposite end of the car, substantially as described.
